Mixer for Broadcast/Podcasts

We're in the process of setting up a small studio for our students to create podcasts. I'm 
looking at a suitable mixer for a PC-based setup (using Adobe Audition). The students will be 
using a mixture of digital recorders and in-studio recording to create the podcasts. 
A broadcast professional has recommended a Soundcraft RM1D for the job, but it seems to 
me that as much of the recording will be in the digital domain already that something like a 
Yamaha 01X might be more suitable as it has a firewire connection and can be used as a 
control surface as well.
I'd be very grateful for any advice in this area.
cheers,
Rog
